=head1 Notice
[ List each enhancement as a =head2 entry ]
-=head2 C<fileno> now works on directory handles
-
-When the relevant support is available in the operating system, the
-C<fileno> builtin now works on directory handles, yielding the
-underlying file descriptor in the same way as for filehandles. On
-operating systems without such support, C<fileno> on a directory handle
-continues to return the undefined value, as before, but also sets C<$!> to
-indicate that the operation is not supported.
-
-Currently, this uses either a C<dd_fd> member in the OS C<DIR>
-structure, or a dirfd(3) function as specified by POSIX.1-2008.

=head1 Security
XXX Any security-related notices go here. In particular, any security
[ List each incompatible change as a =head2 entry ]
-=head2 C<&> prototype accepts only subs
-
-The C<&> prototype character now accepts only anonymous subs (C<sub {...}>)
-and things beginning with C<\&>. Formerly it erroneously also allowed
-C<undef> and references to array, hashes, and lists. [perl #4539]
-[perl #123062]
-
-=head2 C<use encoding> is now lexical
-
-The L<encoding> pragma's effect is now limited to lexical scope. This
-pragma is deprecated, but in the meantime, it could adversely affect
-unrelated modules that are included in the same program.
-
=head1 Deprecations
XXX Any deprecated features, syntax, modules etc. should be listed here.
[ List each other deprecation as a =head2 entry ]
-=head2 Setting C<${^ENCODING}> to anything but C<undef>
-
-This variable allows Perl scripts to be written in a non-ASCII,
-non-UTF-8 encoding. However, it affects all modules globally, leading
-to wrong answers and segmentation faults. New scripts should be written
-in UTF-8; old scripts should be converted to UTF-8, which is easily done
-with the L<encoding> pragma.
-
=head1 Performance Enhancements
XXX Changes which enhance performance without changing behaviour go here.
=item *
-Win32 Perl uses 8 KB less of per-process memory than before for every perl
-process of this version. This data is now memory mapped from disk and shared
-between perl processes from the same perl binary.

=item *
-On Win32, restoring in a child pseudo-process a variable that was
-C<local()>ed in a parent pseudo-process before the C<fork> happened caused
-memory corruption and a crash in the child pseudo-process (and therefore OS
-process).

-
-Calling C<write> on a format with a C<^**> field could produce a panic
-in sv_chop() if there were insufficient arguments or if the variable
-used to fill the field was empty. [perl #123245]

-Non-ASCII lexical sub names (use in error messages) on longer have extra
